Letters` Patent No. 93,105, dated July 27, 1869.

IMPROVIEI'VIENT IN' HYDROCARBO'N-BURNERS.

The vSchedule referred to in these Letters Patent and making part of the same.

To all whom 'it may conce/rn:

Be it known that I, EDMOND l?. MCOAR'IHY, of the city and county of Sau Francisco, State of California, have invented an Improved Device 'for the More Perfeet Combustion of Petroleum; and I do hereby declare the followingdescription and accompanying drawings are sufficient to enable any person skilled in the art or science to which it most nearly appeitains, to make and use my said invention or improvements without further invention or experiment.

My invention relates to that class of burners used for the .combustion of petroleum and other hydrocarbons; and y lt consists in providin g an apparatus by which ordinary wet steam from the boiler is passed from a jettnbe through a peculiarly-shaped pipe, so thatr it forms a partial vacuum, by which means a body of air iscarried in and mixed with the steam.

The oil is discharged into this pipe at a point where it will fall into the blast of mixed steam and air in such a manner th at it is instantly converted into a fine spray, in which condition it enters the furnace, where it is burned with thead of the steam and air, no retort being`.1 1ecessary.

. To more fully explain my invention, reference is had to the accompanying drawings, forming a part of this specification, of which- Figure 1 is a side View of my apparatus.`

Figure 2 is a side sectional view of the same.

Similar letters of reference in each of the iignres indicate like parts.

A is a tube or pipe, with a longitudinal opening, B, through it. this .opening being enlarged so as to be bell-shaped at each end.

A screw-thread is cut on the outside of .the tube A at each end.

On one end is a nut, C, having four converging arms, D D, which meet in a central line a short distance from the plane ofthe nut G.

A jet-tube, E, is screwed into the boss at the junction of the arms, and steam from the boiler passes through'it from the pipe F.

Both the jet-tube and the nut C are adjustable, so that the jet may be introduced or withdrawn from the kopening B to lregulate its effects.

An expanded nozzle, G, screws on the opposite end of the tube A, and serves-as a discharge or burner for the combined vapors.

The oil'is brought in through the pipe H, and drop into the tube I.

This tube ismade bell-shaped at each end, similar to the tube A.

A ange, J, serves to bolt the whole tol the furnace-1 front or cupola.

The operation of my burner is as follows:

Steam is first raised by an ordinary lire to a presslure of five pounds, and then allowed to pass through the jet E into the passage B, thus forming a partial vacuum, which causes a current of air to rush in around the jet E and mingle with .the steam. As soon as the pressure of five pounds is gained, the doors-cf the furnace and ash-pit are closed.A The 'oil being turned on, is caught by the mingled column of steam and air in the tubel before described, and which, by its shape, causes 'the oil to be thoroughly divided and formed into spray or vapor,'which, mixed with the steam and air, is thrown ont tlirough the nozzle G into the furnace in a condition for combustion.v

By this arrangement, retorts are `entrelydone awayv with, the most perfect mingling of the steam, air, and oil-vapor is accomplished, andthe whole is immediately .thrown Out of the nozzle and burned in the lire-box or furnace.

All the diiiiculty is thus avoided whichhas been heretofore experienced from retorts acting as a still in which a hard deposit is formed, and the retort soon destroyed. A much more perfect combustion is effected,

while the device isvery cheap and simple, easily appli-- cable to any furnace.

For producing an intense heat in' :1Ipolas,puddlin gl furnaces, and for the purpose of making steam, it is the most effective yet discovered. y

I do not, however, claim the commingling or mixing of steam, air, and a hydrocarbon for the purpose of combustion, as that has long been practised; but having thus described my invention, v

What I do claim as new, and desire to secure by Letters Patent, is'-v 1. The arrangement of the adjustable steam-pipe E, iu combination with the bell-mouthed pipeA, whereby said pipe E forms a plug to regulate the quantity of air admitted to mingle with the steam, substantially as described.

, 2. The combination and arrangement of the double bell-mouthed pipes A and I, for contracting and allow- In witness whereof, I have hereunto set my hand and seal.
